This illustration shows how NASA's Psyche spacecraft will explore the asteroid Psyche, beginning with Orbit A when it arrives at the asteroid in early 2026. The initial orbit is designed to be at a high altitude – about 435 miles (700 kilometers) above the asteroid's surface. Over the following 20 months, the spacecraft will use its electric propulsion system to dip into lower and lower orbits as it conducts its science investigation. Eventually, the spacecraft will establish a final orbit (Orbit D) about 53 miles (85 kilometers) above the surface. Set to launch in August 2022, Psyche will i…
